Hill Audio


3 channel analogue mixer

Despite its compact size and focused feature set, the Hill Audio LMD-502 can serve a multitude of applications, from one-man bands to podcast production and video post-production. Basically any situation where a single microphone signal needs to be properly pre-amplified and equalized, and then mixed with a range of stereo signals, calls for the LMD-502’s presence. Unlike other mixers of its format, the LMD-502’s microphone input is not limited to dynamic microphones, but can also handle condenser microphones thanks to its switchable +12V phantom power supply. The external power supply, connected to the mixer via a locking connector, provides for low hum and noise and thus outstanding audio performance. A metal case not only provides for an elegant appearance but also ensures rigidity for the use in mobile applications. A small but extremely versatile mixer!
